उत्तर
Let the length of the cuboid be l m.
Breadth of the cuboid, b = 1.5 m
Height of the cuboid, h = 1.15 m
Volume of the cuboid = 34.50 m3
∴ l × b × h = 34.50 m3
⇒ l × 1.5 × 1.15 = 34.50
⇒ l = `34.50/[1.5 xx 1.15]`
⇒ l = `(3450 × 10 × 100)/(100 × 15 × 115)`
= 20 m
Thus, the length of the cuboid is 20 m.
